<script type="text/javascript">
var expression = /<(?:"[^"]*"|'[^']*'|[^"'>])*?\bsrc\s*=(?:\s*"([^"]*)"|'\s*([^']*)'|([^'"> ]*))/ig;
var result = [];
document.getElementsByTagName('textarea')[0].value.replace(expression, function (l, $1, $2, $3) {
result.push($1 || $2 || $3 || '');
});
alert('|' + result.join('|\r\n|') + '|');
</script>
其实用dthml完全可以的吧，正则的话用下面的表达式：
"([^"]*?jpg)"
上面的修改下，最好是这个：
<img.*?src="([^"]*?jpg)"
不好意思再改下：
<img.*?src="([^"]*?)"
喔...
忘记加img了= =,炯...
改下.var expression = /<img\b(?:"[^"]*"|'[^']*'|[^"'>])*?\bsrc\s*=(?:\s*"([^"]*)"|'\s*([^']*)'|([^'"> ]*))/ig;继续沉.
